Peek-a-boo! Astronomers spot 'T-Rex' of galaxies

If there's any one thing astronomers have mixed feelings about, it must be dust. On the one hand, cosmic dust can provide valuable information that can give clues to the origins of the universe, or to life on Earth. On the other hand, it can just plain get in the way.<p>In the case of a humongous …

Hydrogen Bridge Is 20 Times Longer Than The Milky Way

A bridge of gas more than 20 times bigger than the Milky Way has been discovered linking distant galaxies, possibly after a catastrophic collision or near miss.<p>The cloud of atomic hydrogen is the largest known, massing more than all the gas in our own and the Andromeda galaxies combined. It amounts …

APOD: Collapse in Hebes Chasma on Mars (2014 Aug 12) Image Credit & Copyright: ESA/DLR/FU Berlin (G. Neukum) http://apod.nasa.gov/apod/ap140812.html Explanation: What's happened in Hebes Chasma on Mars? Hebes Chasma is a depression just north of the enormous Valles Marineris canyon. Since the depression is unconnected to other surface features, it is unclear where the internal material went. Inside Hebes Chasma is Hebes Mensa, a 5 kilometer high mesa that appears to have undergone an unusual partial collapse -- a collapse that might be providing clues. The above image, taken by the robotic Mars Express spacecraft currently orbiting Mars, shows great details of the chasm and the unusual horseshoe shaped indentation in the central mesa. Material from the mesa appears to have flowed onto the floor of the chasm, while a possible dark layer appears to have pooled like ink on a downslope landing. A recent hypothesis holds that salty rock composes some lower layers in Hebes Chasma, with the salt dissolving in melted ice flows that drained through holes into an underground aquifer. http://www.esa.int/ http://www.esa.int/esaSC/SEMGQOXLDMD_people_0_iv.html http://www.esa.int/Services/Terms_and_conditions Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140812 #APOD

Hubble sees ancient galaxy that acts as enormous magnifying glass

It was a dumbfounding discovery. Using Hubble telescope data, a scientist spotted a "lensing" galaxy that was enormous, extremely distant and acting as a magnifying glass to another ancient galaxy behind it.<p>Kim-Vy Tran was sure she'd flubbed.<p>The Texas A&M scientific researcher was working late, …

Milky Way Has The Mass Of 800 Billion Suns, Study Finds

Weighty matters<p>Astronomers have performed yet another checkup on our home galaxy, this time asking it to step on a scale. The Milky Way has a mass equal to 800 billion suns, according to the team of researchers from Europe, Canada and the U.S. The team also found there's a 95 percent chance that …

Astronomers Puzzle Over New Breed Of Massive Stars

Like fireflies sparking on a hot August night, the universe’s most massive stars run the gamut of their lives in a cosmological blink of an eye.<p>The most massive stars known — the rare, hot O3 spectral type — burn through their hydrogen in something like a million years. Many morph into even rarer …

APOD: Rho Ophiuchi Wide Field (2014 Jul 27) Image Credit & Copyright: Rogelio Bernal Andreo http://apod.nasa.gov/apod/ap140727.html Explanation: The clouds surrounding the star system Rho Ophiuchi compose one of the closest star forming regions. Rho Ophiuchi itself is a binary star system visible in the light-colored region on the image right. The star system, located only 400 light years away, is distinguished by its colorful surroundings, which include a red emission nebula and numerous light and dark brown dust lanes. Near the upper right of the Rho Ophiuchi molecular cloud system is the yellow star Antares, while a distant but coincidently-superposed globular cluster of stars, M4, is visible between Antares and the red emission nebula. Near the image bottom lies IC 4592, the Blue Horsehead nebula. The blue glow that surrounds the Blue Horsehead's eye -- and other stars around the image -- is a reflection nebula composed of fine dust. On the above image left is a geometrically angled reflection nebula cataloged as Sharpless 1. Here, the bright star near the dust vortex creates the light of surrounding reflection nebula. Although most of these features are visible through a small telescope pointed toward the constellations of Ophiuchus, Scorpius, and Sagittarius, the only way to see the intricate details of the dust swirls, as featured above, is to use a long exposure camera. http://blog.deepskycolors.com/ http://www.facebook.com/DeepSkyColors Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140727 #APOD

Keep Calm: The Truth About The Huge Solar Flare That Just Missed Earth

Last night, a friend asked me if I had written about the huge solar flare that nearly converted all of us to an Amish lifestyle. It was a story I was familiar with, but I thought it was old news. After all, the huge Coronal Mass Ejection that could have wreaked havoc on our electric grid and other …

APOD: IC 4603: Reflection Nebula in Ophiuchius (2014 Jul 23) Image Credit & Copyright: Rolf Olsen http://apod.nasa.gov/apod/ap140723.html Explanation: Why does this starfield photograph resemble an impressionistic painting? The effect is created not by digital trickery but by large amounts of interstellar dust. Dust, minute globs rich in carbon and similar in size to cigarette smoke, frequently starts in the outer atmospheres of large, cool, young stars. The dust is dispersed as the star dies and grows as things stick to it in the interstellar medium. Dense dust clouds are opaque to visible light and can completely hide background stars. For less dense clouds, the capacity of dust to preferentially reflect blue starlight becomes important, effectively blooming the stars blue light out and marking the surrounding dust. Nebular gas emissions, typically brightest in red light, can combine to form areas seemingly created on an artist's canvas. Photographed above is the central part of the nebula IC 4603 surrounding the bright star SAO 184376 (actually 8th magnitude) which mostly illuminates the blue reflection nebula. IC 4603 can be seen near the very bright star Antares (1st magnitude) toward the constellation of Ophiuchus. http://www.rolfolsenastrophotography.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140723 #APOD
